I'd like to find a lightweight .22LR revolver. Something like the S&W 317 AirLite with the 3" barrel. I just don't see why a .22 should weigh as much as a .44mag. Last year I bought a Taurus 94, which is 25 oz, but the S&W is 12 oz. Quite a difference. I'm wondering if it would be worth the upgrade. Has anyone tried one? Is it worth the extra $$?
